Bug ID: 95367 Summary: gcc crashed Product: gcc Version: 11.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c Assignee: unassigned at gcc dot gnu.org Reporter: ferruh.yigit at intel dot com Target Milestone: --- Created attachment 48619 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=48619&action=edit the gcc output with "-v -save-temps" Please find below gcc log [1] and the source file it builds [2]. gcc version [3] is compiled from source, the commit of the source it has been built is [4]. And full command line to build is [5]. Also compiled with additional "-v -save-temps" parameters, the gcc output (gcc_verbose_command_output.txt) and the .i file (hinic_pmd_nicio.i) are also attached.
